irregardless is not a word

ironic misused by every turd

penultimate IS NEXT TO LAST

ultimate is last— NOT BEST 

but could be MAX or HIGHEST

acute is sharp

chronic is long-lasting

accept or except

neither, notwithstanding

adverse is contrary

while averse, strongly opposed

affect and effect

make me scratch my nose

redundant doesn’t mean useless, goof!

grab a dictionary and see the proof

and, overestimate and underestimate

might cause you some confusion

as will lose-loose,  jive-jibe— allusion and illusion

however,

I assure you that I ensure to insure my car.
